android模块，android:attr/ttcIndex & android:attr/fontVariationSettings

Question

我正在将我所有的支持/appcompat库迁移到androidx。毕竟，由于这个错误，我无法构建我的项目

:app:processDebugManifest UP-TO-DATE
AGPBI: {"kind":"error","text":"error: resource android:attr/fontVariationSettings not found.","sources":[{"file":"/Users/xxx/.gradle/caches/transforms-1/files-1.1/appcompat-v7-27.1.1.aar/7cae290a69b05f5ffc25283e26a7eb4a/res/values/values.xml","position":{"startLine":250,"startColumn":4,"startOffset":27058,"endColumn":68,"endOffset":27122}}],"original":"","tool":"AAPT"}
AGPBI: {"kind":"error","text":"error: resource android:attr/ttcIndex not found.","sources":[{"file":"/Users/xxx/.gradle/caches/transforms-1/files-1.1/appcompat-v7-27.1.1.aar/7cae290a69b05f5ffc25283e26a7eb4a/res/values/values.xml","position":{"startLine":250,"startColumn":4,"startOffset":27058,"endColumn":68,"endOffset":27122}}],"original":"","tool":"AAPT"}
:app:processDebugResources

我试图逐个包含所有的依赖项，以确定是哪一个引起了问题。只有当我移除房间库¯\_(ツ)_/ツ时，我才能构建

https://developer.android.com/topic/libraries/architecture/adding-components#room

这很奇怪，因为问题似乎来自风格化的资源，但空间只是一个数据库库。

是指在不破坏一切的情况下有任何想法或解决方案来包含空间的人吗?

===============================

我的公寓：

compileSdkVersion 27
buildToolsVersion 27.0.3

defaultConfig {
    minSdkVersion 16
    targetSdkVersion 27
}

dependencies {
    // ROOM
    implementation ('androidx.room:room-runtime:' + androidxRoomVersion)
    implementation ('androidx.room:room-rxjava2:' + androidxRoomVersion)
    implementation ('androidx.room:room-guava:' + androidxRoomVersion)
    kapt ('androidx.room:room-compiler:' + androidxRoomVersion)
}

带: androidxRoomVersion =2.0.0-字母1

Answer 1

设置您的compileSdkVersion 'android-P'和targetSdkVersion 28

编辑： Now compileSdkVersion 28也应该工作，这意味着您不必再将其设置为android-P

Answer 2

将compileSdkVersion改为“android-28”，将targetSdkVersion改为“28”

Answer 3

如果其他人因为最近在您以前工作的优秀中突然发现这个错误而遇到了这个问题，那么您就可以对本机项目做出反应--这是由于Google服务和Firebase中的最新变化所致。特别是你会对依赖于-

com.google.android.gms:play-services-gcm

先检查一下这条线-
